Nstreme-dual signal graphing

Would it be possible to get an OID that returns signal strength for the cards used in an nstreme-dual link ? or even an extra option like

/in wi nstreme-dual status

that would return something like
0:
tx:-67
rx:-64
1:
tx:-61
rx:-62

so it can be retrieved . Or maybe i’m missing out how to get the strength

I am trying to get this working using MRTG, but i cannot seem to get the radio to respond. I have found the OID’s but i only get an “End of MIB” response when I to an snmpwalk.
Any ideas? Here are the OID’s I found.

Flags: X - disabled, R - running
0 R tx-rate=.1.3.6.1.4.1.14988.1.1.10.1.1.2.10
rx-rate=.1.3.6.1.4.1.14988.1.1.10.1.1.3.10
tx-signal-strength=.1.3.6.1.4.1.14988.1.1.10.1.1.4.10
rx-signal-strength=.1.3.6.1.4.1.14988.1.1.10.1.1.5.10
connected=.1.3.6.1.4.1.14988.1.1.10.1.1.6.10

Thanks
